ALEXANDER C. FRANKEL, OF NEWARK, NEW JERSEY, ASSIGNOR TO JACOB LAGOWITZ,OF SAME PLACE.

CASTER.

SPECIFICATON forming part of Letters Patent No. 338,636, dated March 23,1886.

Application filed December 11, 1885. Serial No. 185,376. (No model.)

To all whom it may concern:

Be it known that I, ALEXANDER O. FRANK- EL, of Newark, in the county ofEssex and State of New Jersey, have invented certain new and usefulImprovements in Casters, of

which the following is a specification.

My invention consistsin a caster for trunks, furniture, &c., consistingof a frame or casing bent up from a suitable sheet-metal blank Io andpivoted to a top plate, a main roller carried by an aXle in said frame,and a smaller roller carried by the outer or moving end of said frameand adapted to bear against the top plate of the caster.

In the drawings, Figure lis a perspective view of my improved caster;Fig. 2, a sectiouvon the line .r xof Fig. 1, Fig. 3, a section on theline y y of Fig. 2, and Fig. 4 a detail view.

The purpose of my invention is to provide a caster which shall withstandrough usage and answer quickly to any change of direction given to thearticle to which it is applied. y

A indicates the casing or sheath, made preferably of a single piece ofsheet metal, of the form shown in Fig. 4, and bent up to proper form, asshown in Figs. 1, 2, and 3 and by dotted lines in Fig. 4. The sheath orcasing has two side lips, a, and an intermediate tongue, b, perforatedat suitable points, as shown, for the pivots of the two rollers orwheels and for the attaching-pivot.

Bindicates the Inain roller or wheel, said wheel being free to rotateupon its pivot-pin c, riveted at each end in the side wings, a, of thecasing or sheath A, as shown in Fig. 3.

C indicates the pivot or journal by which the caster is secured to itstop plate, d, which latter is in turn secured to the article on whichthe caster is to be used. The pivot C is riveted to the sheath or casingA and to the plate d, as clearly shown in Fig. 2, care being taken toallow a little space between the sheath or casing and the plate d, asshown in Figs. 2 and 3.

As shown clearly in Figs. 1 and 2, the tongue b of the sheath or casingA is bent downward at the point of juncture with the lips a a, at

right angles thereto, is then bent outward at 5o right angles, andfinally bent upward again at right angles until its outer end isnearlyin line with the top of the sheath, as shown. Vhen thus bent, itwill be seen that the tongue I) forms a socket for the friction-wheel D.

The friction-roller D is journaled and free to rotate upon a spindle, e,riveted in the tongue b, as shown, said spindle being at right angles tothe spindle c of wheel B.

The wheel D bears upon the plate d, as 6o shown in Fig. 2, at about thesame distance in rear of the axis of wheel B as the pivot C is in frontofthe latter.

From this construction it will be seen that the Wear is equal ydistributed 011 the pin c and friction-roller D, as each is the samedistance 'from the bearing-point of wheel B.

The casing may be of cast metal, if preferred, and its design andproportions may vary as desired. 7o

Instead of a rivet connecting the top plate and the casing or frame, apin may be cast upon or attached to one of said parts and arranged toenter a socket in the other.

I am aware that it is not broadly new to place the friction-wheel andthe pivot of a caster respectively in rear and in advance of the pivotof the main Wheel.

Having thus described my invention, what I claim isl. A casing forcasters iliade of a single piece of sheet metal and provided withasocket for the main wheel and socket for a frictionwheel, substantiallyas shown.

2. The herein-described caster,consisting of the top plate, asheet-metal frame or casing pivotally connected therewith and havingsides a v and portion b, roller B, mounted upon an axle between thesides a a, and roller D, carried by an axle in the part b and ar- 9oranged to bear against the plate at the end of the casing farthestremoved from the pivot of said casing.
